Performance Analysisof Orbit Determination Algorithms. For Space Surveillance& Tracking in LEO

      Аннотация: Space Surveillance and Tracking (SST) is an increasingly necessary field of research due to the exponential growth of debris. During this work several space environments are going to be simulated while surveillance and tracking is performed.First, a brief opening of the SST history and main problems is presented.Then, in the methodology part, two methods of orbit determination are depicted: Initial Orbit Determination (IOD) and Statistical Orbit Determination (SOD).Afterwards, the software simulation and space environment modelling is deeply explained.Finally, in the last part of the thesis, all these algorithms and their parame-ters are compared through several usual metrics.Along this book the simulation of this space debris problem and its analys is through SST techniques is going to be developed in various scene environments trying to reach the most optimal tracker for each of them.
